Or do you mean that hw_params must always be called before prepare, but it's possible to call hw_params again after prepare, provided one then calls prepare again before trigger? If that is the case, wouldn't it work to allocate the DMA buffer the first time prepare is called? _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
